Won’t see my daughter for a week

My baby is 2 and a half years old and me and her father share custody nearly 50/50. Which is awesome and I trust him and love that they have a close bond.

Sooo... in a week me and her are leaving to go on a trip to visit my family in CT (we live in CA so it’s pretty far) for a week. Then the day after we get back, her dad and his family are taking her on a 9 hour roadtrip to Reno, they will be gone four days and then the last three days she’s back are “his” days for custody so I won’t see her for an entire week.

In our custody agreement we each are allowed one week of vacation with her per year and this will be my second one and his first. So...I have NO ROOM to complain or tell him he can’t go.

I’m just irrationally worried. I have never been away from her for a week and also the thought of her being in a car for so long worries me so much even though they are all good drivers... the thought of her being so far away and in a touristy area makes me worry too. Plus its a lot of traveling for her so close together.

I’m so fucking stressed because I already have severe post partum OCD (intrusive thoughts about something bad happening to her, panicking and obsessing over her safety and paranoid about really unlikely tragedies all the time) and this is making it go through the roof. I know I should just use the time to keep busy and be productive but I don’t know how im going to survive.

I know I’m being overly protective. Her dad and his family are great and obviously know how to take care of her but I’m gonna miss her so much I’m going to go insane and I know I’m taking her for a week too so it’s literally the same thing but me and her are much closer we’re inseparable I’m so freaked out ugh. Someone PLEASE HELP ME SEE THE POSITIVES to this....🥺
